Oracle Essbase 9 Implementation Guide- P29:Essbase is a multidimensional database management system. The name Essbase stands for Extended Spread Sheet dataBASE. Using the custom add-in provides the end-user with near seamless compatibility in the Microsoft Excel spreadsheet program. | Chapter 4 Relational databases We have saved the best for last Without the time or expense of writing complicated interfacing programs Essbase allows you to create a data load rule that automatically connects directly to an external relational database such as Teradata or SQL Server just to name a few. Using a load rule with connection information specified you actually write an SQL query using the source database s own Structured Query Language SQL commands. You can use this data source to build the outline itself or to load the data values. By now you should be telling yourself just how cool you think Essbase is and what did you ever do before you learned about it. Data load methods We have discussed the types of data you can load into your Essbase database. We have also discussed how these types of data can be loaded as just the data values themselves or that they can be used to build your Essbase database outline by dynamically adding dimension members and then loading the data values. Here we will discuss some of the various methods you can use to load data into your Essbase database. Data file freeform no load rule This method is quite possibly the most worry free and easy way to load data into an Essbase database. When you have a properly formatted Essbase-friendly data file all you need to do is drag-and-drop the file onto the EssCmd MaxL executable files or their desktop shortcuts. Essbase will automatically determine what delimiter you are using and correctly load the data. Here are just a few words of caution on using this data load method. The reason it is so easy at the load step is because the harder work has already been done at the front of this process to create an Essbase-friendly data source. If you were to create such a program it would need to construct your data source file in such a way as to match the structure of the database outline. Each field in every row of data in the file would need to contain a representative member from every .
